A0.120 kg baseball, thrown with a speed of 38.4 m/s, is hit straight back at the pitcher with a speed of 47.3 m/s. (a) what is the magnitude of the impulse delivered by the bat to the baseball? kg · m/s (b) find the magnitude of the average force exerted by the bat on the ball if the two are in contact for 2.20 10-3 s. kn

10.284 kgm/s

4.674545 kN

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

m = Mass of baselball

Impulse

Impulse of the baseball is 10.284 kgm/s

Impulse is also given by

The magnitude of the average force exerted by the bat on the ball is 4.674545 kN

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
